I have an original Caves of California book copy #90 of this very rare 1962 William R. Halliday book for sale. Of the 500 copies of this book that were printed 51 years ago, 175 copies were lost in a "flood". A signed copy sold on this site about 8 years ago. The asking price was $600 but I don’t know what it sold for. Here is the link to that thread. viewtopic.php?f=16&t=198&p=1959&hilit=+caves+california#p1959

I am now offering my Caves of California copy #90 for sale. I am asking $400 plus $5 shipping for this very rare book. The book is in excellent condition with no writing, tears, dog eared pages, or stains. The only damage, if you can call it damage is the lower right corner of the front as shown in the photo. Otherwise, this book is in like-new condition.

I am selling my 30 year cave book collection a little at a time. If you are looking for a particular hard to find or rare cave book, let me know and I will look to see if I might have a copy.
